BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to display technical field, especially toa pallet and a packaging case.

2. Description of Related Art

With the appearance and development of all kinds of liquid crystalproduct, the liquid crystal displays are widely used in all trades andprofessions, and every corner of the modern life. In a liquid crystaldisplay, a liquid crystal panel is its key component. When manufacturingthe liquid crystal displays, due to division of work, a mass of theliquid crystal panels are transported to other place to be furtherprocessed modularly.

In prior art, packaging boxes made of foam materials are usually used topackage and protect the liquid crystal panel. The packaging boxes withpackaged liquid crystal panels are stacked on the pallets and are baledand fixed to be transported safely. Since the liquid crystal panels havedifferent sizes for different liquid crystal displays, packaging boxeswith different sizes are also required. However, the larger packagingboxes need larger pallets to be stacked thereon. The disadvantages areas follow: 1. the load bearing surface of the pallet is flat. The palletis only used to stack the packaging boxes with packaged products so thatcannot be used to package the products. 2. After the packaging boxes arestacked, the wrapping belts and friction between the pallet and thebottom surface of the bottommost packaging box stabilize the packagingbox. When the packaging cases are transported, the packaging cases arevibrated and shaken within the trunk. When the shaking force is larger,the bottommost packaging box slides on the pallet so as to tilt thepackaging case. Then the adjacent packaging cases may bump against eachother or hit the inner wall of the trunk. Therefore, the packaging casesmay suffer exceeding force in some parts to cause the liquid crystalpanels inside the packaging boxes damage. 3. Packaging boxes with largesize need to order corresponding pallets with large size. In particular,with the variation of the sizes of the liquid crystal panels, packagingcost is further increased while packaging boxes with corresponding largesize are needed.
